We will be crossing lots of creeks on this trip and if you remember our last visit to the north the navigator refused to walk the creeks before driving across. Well some of them might have some crocs lurking in them but we wouldn't want to get stuck half way across! So to solve the problem we are taking a creek walker with us this time plus a spare one in case the first one gets used up quickly! They are called Brian and Josie and they think they are on holiday but don't let on!!
